Question

"Brad is trying to determine the Cp of a process. The USL is 10, the LSL is 2, and the standard deviation is 1. What is the Cp"

Answer 1

Answer:

1.33

Step-by-step explanation:

Given that:

Upper specification limit ( USL ) = 10

Lower specification limit ( LSL ) =  2

the standard deviation σ =  1

What is the Cp"

The Cp is the process capability ratio which can be expressed by the formula:

$C_P = \dfrac{USL -LSL}{6 \times \sigma}$

$C_P = \dfrac{10 -2}{6 \times 1}$

$C_P = \dfrac{8}{6}$

$C_P = \dfrac{4}{3}$

$C_P =1.33$
